PRNP(redirected from CD230 antigen)
Also found in: Wikipedia.
PRNPA gene on chromosome 20p13 that encodes a membrane glycosyl-phosphatidylinositol-anchored glycoprotein, which aggregates into rod-like structures and contains a highly unstable region of five tandem octapeptide repeats. The exact function of PrP is unknown.
PRNP mutations are linked to Creutzfeldt-Jakob disease, fatal familial insomnia, Gerstmann-Straussler disease, Huntington-like disease 1 and kuru.
